In our veritas netbackup for DB2 on AIX, the backup could be done
successfully and the backup image would be listed using bplist on the
AIX client.

I have made several backup image, but only one image would be restored
successfully. Restore with all the other images would get
SQL2025N An I/O error "515" occurred on media "VENDOR".

Does anyone has any idea on it?

Thanks.

1. In the first line from the NetBackup "bpdb2" log, the 900 second
(15 minute) timeout is the default for CLIENT_READ_TIMEOUT.
CLIENT_READ_TIMEOUT should be longer than it takes to backup your
largest tablespace, and should be set in the "/usr/openv/netbackup/
bp.conf" file on your client AND media server. For instance, to
increase this to 30 minutes add:

CLIENT_READ_TIMEOUT = 1800

2. The second line from the NetBackup 'bpdb2" log shows "could not
read from comm file". This is the progress log that is stored on the
client. All the NetBackup processes involved in the backup need access
to this file. Make sure that the user that is backing-up DB2 has read/
write permissions to the "/usr/openv/netbackup/logs/user_ops/dbext/
logs" directory.

3. Also check connectivity between the client and the other servers in
the configuaration (master and media).

4. All else fails, open a case with Symantec.

Hope this helps.
